I recently returned from a trip to Tiger Beach and Bimini on the Dolphin Dream. The dive below likely represents the lower limit of my RMV while diving, 0.24 cu ft/min. We descended to about 33 feet and stood or kneeled on the sand bottom while waiting for Great Hammerheads to swim through the feeding station. I was nice and warm, the water was 80 degrees and I was wearing a full 5 mm and a 5/3 mm hooded vest. The lowest RMV I have ever had on a normal dive was 0.26 cu ft/min Average Gas Consumption My average RMV is 0.36 cu ft/min. I find it interesting that the 0.24 is 3 standard deviations below my average, representing 99.7% of all values

Just goes to show that kneeling on the bottom in 33' of 80 degree water isn't a real dive.

<<Kidding>>

It's not a normal dive. There were moments of great excitement though

So, I already posted one of my dives to Tiger Beach and Bimini, here is a second. This is probably the longest dive I have done off an AL80, 2:15 of dive time. Of course, this is not a normal dive, mostly standing or kneeling in the sand watching sharks go by at 2 atm. Nevertheless, a long dive using 76 cu ft of air.

Another 1000 views, now >28,000, and another 11 votes in the poll. I would imagine this is the largest sample of average RMVs available, does anyone know different?

mostly standing or kneeling in the sand

Isn't kneeling on the bottom bad for you? (I don't know about standing, but there must be a very strict rule against it somewhere).

What is the purpose of your post? This was a baited, feeding shark dive, purposely executed in a large, open sandy area, where no damage is done to the reef

This was clear in your earlier post I do not think you need to explain it again. Great dive it seems wish I could join you on a shark feeding dive.
